Japanese Barware

In Japan, the Highball is one of the most popular drinks at bars and izakayas, and its namesake glass is as ubiquitous as the pint glass at any pub. With the traditional diamond cut pattern at the base of each glass, these Diamond Cut Highball Glasses bring elegance to your drinks. And made with Toyo-Sasaki's Hard Strong Gold glass-strengthening technology, you can be sure they're utterly durable and dishwasher safe.

Testimony by an Umami Mart customer:

“I dropped a Hard Strong glass on my granite counter top, then it bounced into my steel sink and nothing happened! I saw it with my own eyes in slow motion, sure it was going to shatter during the tumble. These are truly Hard Strong!”

*This testimonial was given in March 2014, in regards to the Striped Double Rocks Glass, which has the HS Platinum grade protection. Glassware breakage is inevitable but the extra HS coating (plus good care and a little luck) helps to prevent it when possible. Read more about the Hard Strong technology here.
